Hinge Doors

There has been a rise in having oversized hinged doors. These doors can be used as interior doors and exterior doors of buildings and homes. Hinged doors are one of the most common doors built in the industry.

A hinged door with Sing Core inside can be any size. The greatest majority of Sing doors sizes are 4×8 hinged doors and larger, up to 50 ft tall large oversized doors (or more). The main reason why only the best architects specify having Sing Core inside their large doors is due to the unique characteristics of patented Sing Core, which helps to create the only Eco-friendly, lightweight, high strength hinged doors
